Subject: RE: 770 auto shutdown problem
Hi,
I found your post googling a bit because I have the same problem. I
couldn't
post directly at:
http://www.mail-archive.com/maemo-developers%40maemo.org/msg08919.html
My N770 shutdowns randomly, sometimes it is possible to get it back, but
most
of the time I have to switch it on again. It is very annoying.
I think the trick here is that the N770 shuts down after a while if
there is
nothing to do. I've noticed that if I play music, the nokia does not
dies and
behaves correctly all the time. Perhaps it is not ypur case.
Probably creating a 'stay-alive' app to the dbus could fix the
problem.... I
have to take a look at this.
In case I find something new I'll let you know.
Thanks for the post!

Dear All,
Thanks for your comments on my shutdown problem, sorry its taken a while
to get back to you but I was waiting for a new battery and being on
holiday!
So: I reflashed the unit (latest 2006) and put it in R&D mode (green
info text on startup) and I was still seeing the same problem, namely
the 770 decides to turn itself off rather than entering a low power
standby state after a period of inactivity.
I bought a new battery and have tried that too and I am getting the same
problem.
Even with the old battery, energy levels are not low, I can use the
device for ages on constant usage its just if I close it, when I come
back (even after a short time, say 10 minutes) the device is dead.
Apart from monitoring the dbus, does anyone have an idea on how I can
try to trace what's happening when it shuts down? Are there any clever
ways of recording the sequence of events that would lead to a shutdown?
Does anyone know the logic that leads to shutdowns or stanby actions?
Is the code that governs this open? Could someone point me to it?
Thanks
John
